What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
What kind of tests is a megger used for?
A megger is an instrument that generates a high voltage. That high voltage is then used for measuring insulation resistance, especially that of electrical devices.
How do you use a multimeter?
A multimeter is an instrument used to check for AC or DC voltages, resistance and continuity of electrical components, and small amounts of current in circuits. This instrument will let you check to see if there is voltage present on a circuit.
What is meggers?
A megger is an electrical instrument that is used to measure the resistance of insulation by applying a DC voltage to the conductor. One lead is connected to the conductor and the other lead is connected to ground. Safe insulation reading to ground should be above 2,000,000 ohms or 2 megs.
The unit of electrical resistance is the?
The ohm is used to measure electrical resistance. Plural ohms. With a lil bit of koolaid.The ohm is an international standard unit of measure.Further informationThe basic unit of electrical resistance was given the name "The ohm" in honor of Georg Ohm.Georg Ohm invented the basic electrical law:Resistance (measured in ohms) = voltage (measured in volts) divided by current (measured in amps)which was later given his name: Ohm's Law.Ohm's Law can also be used to find voltage and current when it is expressed as:Volts = amps x resistanceandAmps = volts / resistance.Another answerThe S.I. unit of electrical resistance is the ohm, symbol Ω (omega).1Ω is defined as the resistance of a conductor which allows a 1 ampere of current to flow through it when a potential difference of 1 volt is applied.ohms
What electrical measuring instrument is used to measure polarity index test?
A low resistance ohmmeter is used
What instrument measures voltage in a current?
Resistance is the name given to something which opposes the flow of an electrical current in a circuit and an ohmmeter is used to measure it.The Ohm is the name of the unit used to measure resistance.Further noteThe most common type of instrument used to measure resistance is a multimeter, which includes an ohmmeter, an ammeter to measure the current flow in amps and a voltmeter to measure the potential difference in volts.

What is an absorption dynamometer?
An absorption dynamometer is an instrument used to measure force, by measuring the energy absorbed via friction or electrical resistance.
What is the name of an instrument for measuring electrical current?
Electrical current can be measured with an Ammeter. The units used are amps.
What kind of tests is a megger used for?
A megger is an instrument that generates a high voltage. That high voltage is then used for measuring insulation resistance, especially that of electrical devices.
What symbol is often used for electrical resistance?
I have never come across a symbol for an electrical resistance box. As the resistance box is a test instrument and it would not be drawn on any electrical schematic there may not be a symbol designated for it. The last letter of the Greek alphabet is (Ω omega) and it is used for the electrical symbol for resistance.
What instrument is used to vary electrical resistance in a device?
Virtually all electrical devices (actually, all except for superconducting devices) have resistance. There is one type of electrical device that is found in almost every electronic circuit ever invented. It is used wherever the designer needs a specific amount of resistance in the circuit. I'd hate to spoil your fun by simply telling you its name. Think of all of the different names of electrical devices that your teacher has told you about. (or look in the index of your text book if you're in a hurry) Is there one that comes to mind when you think of RESISTance?

Ohm meter mean and their use?
An ohmmeter is an electrical instrument that measures electrical resistance, but instead of hairsprings to supply a restoring force they used conducting of the first pair of leads and their contact resistances is ignored by the meter.
Does sugar create electrical resistance?
Sugar is not used in electrical circuits.
